I think my the Omni 6's logic board finally took a dump. The display and key 
functions have froze up and resetting won't change anything. Pressing buttons 
gives a beep but doesn't change the display, modes, filters or anything else.
The voltages and clock signals to the various IC's are all there and I reseated 
all the IC's and connectors.
I suppose there aren't any working logic boards for these rigs out there since 
it seems it's the first item to go and then the radios get parted out.

Rather than part this one out, I'm wondering if I could just use a Si5351 and 
Arduino to get this to work again.
No, it wouldn't have the advantage of that low phase noise PLL but at least it 
would keep it out of the junk pile.
I would use an Arduino to control a Si5351 DDS to output the 5 to 5.5 MHz and 
to control which LO and filters get selected.
Any thoughts?
Curt, K8AI
